摘要： PURPOSE:To perform the automatic bumpless transfer, by using a rate limiter which has the proportional aging characteristics of output to an input. CONSTITUTION:When a control mode command device 21 is selected to the back pressure control from the front pressure control, the output of a PI controller 14 is selected by a changeover switch 20. In this case, the output of a rate limiter 30 keeps at first the output of a PI controller 12 for front pressure, and therefore a changeover switch 37 is set at the M side by the output of an AND element 36. Thus the output of the switch 37 has no sudden change. Then the output of the limiter 30 approximates to the output of the controller 14, and the switch 37 is changed to the N side by the output of the element 36. As a result, the output of the controller 14 is sent to an operating device 18. Thus the control mode is automatically switched with no bump. In such a way, the bumpless transfer is automatically carried out.

摘要： PURPOSE:To improve the follow-up property of a bypass valve by a method wherein the amount of flow inproportion to the output required to a turbine is flowed inpreference to a governor valve and the amount corresponding to the subtraction of said amount from a controller output is discountedly allotted to the bypass valve for the control by anticipatory estimate. CONSTITUTION:The output of a controller 40, into which pressure deviation is inputted, is sent to a low value selector 41 and the signal of the output, which subtracts the output of the low value selector 41 from said output of the controller 40, is sent to a subtractor 42 in order to control the bypass valve 7. The output of the low value selector 41 is also sent to a multiplier 30, the output of which is sent to an operating unit 14 for the governor valve 5. The output of the subtractor 42 is sent to a multiplier 27, the output of which is sent to an operating unit 15 for the bypass valve 7. Because the turbine is controlled by anticipatory estimate by means of the bypass valve 7 in such a manner as described above, the control delay of the bypass valve 7 is eliminated, resulting in enabling to prevent the pressure within the inlet piping of the turbine from abruptly charging.

摘要： PURPOSE:To enable economical operation even when the discharge pressure of a pump is varied markedly by installing a flow rate detector on the upper stream side of the pump and a pressure detector on the lower stream side and comparing the difference of the both signals with the signal from the differential pressure. CONSTITUTION:A flow rate detector 10 is installed the upper stream side of a pump 1, and a pressure detector 9 is installed on the lower stream side, and in an adder 12, the signal from the pressure detector 9 is subtracted from the signal from the flow rate detector 10, and the output is compared with the signal from an adder 6 by means of a high selector 13. Therefore, in the operation where the flow rate more than at a point 16 is necessitated, the signal from the adder 12 becomes larger than the signal from the adder 6, and the signal of the adder 12 is selected in the high selector 13, and the operation along overload line 15 is formed. Thus, even if the discharge pressure varies markedly, economical operation is permitted.
